What I'm looking for

I'm looking to build scalable quality automation for distributed, microservices-based products, improving CI/CD feedback, API reliability, and release confidence across collaborative engineering teams.

I've improved release quality at HRS Hospitality and Retail Systems, Bright Security, and Sberbank by building and expanding automation across APIs, UI, databases, and microservice integrations. At HRS, I designed a multi-layer API and E2E automation framework and introduced contract validation for microservices and GraphQL gateway integrations.

My work spans JS/TS, Java, and Python testing solutions using Playwright, Selenium, REST Assured, CI/CD pipelines, and modern API protocols. I've supported credit-card services handling millions of daily transactions, reduced repetitive manual testing at Bright Security by 27%, and increased automated API regression coverage at Sberbank by 18%.
